Rails engine for static pages.

... but be careful. Danger!

Yeah, like "About us", "Directions", marketing pages, etc.

There are two ways to install High Voltage.

You can run:

$ gem install high_voltage

Or you can include in your Gemfile:

gem 'high_voltage', '~> 3.1.2'

Write your static pages and put them in the RAILS_ROOT/app/views/pages directory.

$ mkdir app/views/pages
$ touch app/views/pages/about.html.erb

After putting something interesting there, you can link to it from anywhere in your app with:

<%= link_to 'About', page_path('about') %>

You can nest pages in a directory structure, if that makes sense from a URL perspective for you:

<%= link_to 'Q4 Reports', page_path('about/corporate/policies/HR/en_US/biz/sales/Quarter-Four') %>

Bam.

You can also get a list of your static pages by calling HighVoltage.page_ids This might be useful if you need to build a sitemap. For example, if you are using the sitemap_generator gem, you could add something like this to your sitemap config file:

HighVoltage.page_ids.each do |page|
  add page, changefreq: 'monthly'
end

By default, the static page routes will be like /pages/:id (where :id is the view filename).

If you want to route to a static page in another location (for example, a homepage), do this:

get 'pages/home' => 'high_voltage/pages#show', id: 'home'

In that case, you'd need an app/views/pages/home.html.erb file.

Generally speaking, you need to route to the 'show' action with an :id param of the view filename.

High Voltage will generate a named route method of page_path. If you want to generate your own named route (with the :as routing option), make sure not to use :page as it will conflict with the High Voltage named route.

You can configure the root route to a High Voltage page like this:

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.home_page = 'home'
end

Which will render the page from app/views/pages/home.html.erb when the '/' route of the site is accessed.

Note: High Voltage also creates a search engine friendly 301 redirect. Any attempt to access the path '/home' will be redirected to '/'.

You can remove the directory pages from the URL path and serve up routes from the root of the domain path:

http://www.example.com/about
http://www.example.com/company

Would look for corresponding files:

app/views/pages/about.html.erb
app/views/pages/company.html.erb

This is accomplished by setting the route_drawer to HighVoltage::RouteDrawers::Root

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.route_drawer = HighVoltage::RouteDrawers::Root
end

The default routes can be completely removed by setting the routes to false:

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.routes = false
end

If you are using multiple Rails engines within your application, you can specify which engine to define the default HighVoltage routes on.

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.parent_engine = MyEngine
end

We suggest using content_for and yield for setting custom page titles and meta-data on High Voltage pages.

# app/views/pages/about.html.erb
<% content_for :page_title, 'About Us - Custom page title' %>

Then print the contents of :title into the layout:

# app/views/layouts/application.html.erb
<title><%= yield(:page_title) %></title>

High Voltage uses a default path and folder of 'pages', i.e. 'url.com/pages/contact', 'app/views/pages'.

You can change this in an initializer:

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.content_path = 'site/'
end

Built in caching support has been removed in HighVoltage. See PR 221.

Page caching and action caching can be done via Rails. Visit the Caching with Rails: An overview guide for more details. You can utilize the methods described there by overriding the HighVoltage controller as described below.

Most common reasons to override?

• You need authentication around the pages to make sure a user is signed in.
• You need to render different layouts for different pages.
• You need to render a partial from the app/views/pages directory.
• You need to use your own Page resource and would like to use StaticPage resource for high voltage

Create a PagesController of your own:

$ rails generate controller pages

Disable the default routes:

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.routes = false
end

Define a route for the new PagesController:

# config/routes.rb
get "/pages/*id" => 'pages#show', as: :page, format: false

# if routing the root path, update for your controller
root to: 'pages#show', id: 'home'

Then modify new PagesController to include the High Voltage static page concern:

# app/controllers/pages_controller.rb
class PagesController < ApplicationController
  include HighVoltage::StaticPage

  before_action :authenticate
  layout :layout_for_page

  private

  def layout_for_page
    case params[:id]
    when 'home'
      'home'
    else
      'application'
    end
  end
end

To set up a different layout for all High Voltage static pages, use an initializer:

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.layout = 'your_layout'
end

To use StaticPage resource, turn off routing and use this route:

get "/static_pages/*id" => 'high_voltage/pages#show', as: :static_page, format: false

You can further control the algorithm used to find pages by overriding the page_finder_factory method:

# app/controllers/pages_controller.rb
class PagesController < ApplicationController
  include HighVoltage::StaticPage

  private

  def page_finder_factory
    Rot13PageFinder
  end
end

The easiest thing is to subclass HighVoltage::PageFinder, which provides you with page_id:

class Rot13PageFinder < HighVoltage::PageFinder
  def find
    paths = super.split('/')
    directory = paths[0..-2]
    filename = paths[-1].tr('a-z','n-za-m')

    File.join(*directory, filename)
  end
end

Use this to create a custom file mapping, clean filenames for your file system, A/B test, and so on.

Rails I18n guides.

Add a before filter to the Application controller

# app/controllers/application_controller.rb
before_action :set_locale

def set_locale
  I18n.locale = params[:locale] || I18n.default_locale
end

Disable the default High Voltage routes

# config/initializers/high_voltage.rb
HighVoltage.configure do |config|
  config.routes = false
end

# config/routes.rb
scope "/:locale", locale: /en|bn|hi/ do
  get "/pages/:id" => "high_voltage/pages#show", :as => :page, :format => false
end

Add a static page to the project

# app/views/pages/about.html.erb
<%= t "hello" %>

Make sure that there are corresponding locale files

/config/locale/bn.yml
/config/locale/en.yml
/config/locale/hi.yml

One last note is there is a known issue with High Voltage.

You'll need to specify routes like this <%= link_to "About Us", page_path(id: "about") %>

You can test your static pages using RSpec and shoulda-matchers:

# spec/controllers/pages_controller_spec.rb
describe PagesController, '#show' do
  %w(earn_money screencast about contact).each do |page|
    context "on GET to /pages/#{page}" do
      before do
        get :show, id: page
      end

      it { should respond_with(:success) }
      it { should render_template(page) }
    end
  end
end

If you're not using a custom PagesController be sure to test HighVoltage::PagesController instead.
